He's the world's deadliest assassin-she's the woman who makes him question everything. Dylan "The Ghost" Mercer lives by one rule: no attachments. Emotions are weaknesses he can't afford. But when a high-stakes contract draws him into Sophia Hartley's orbit, his steel-cold fa ade begins to crack. Sophia has built her life fighting her family's criminal shadow, enforcing justice by day-and battling ghosts at night. She never expected to meet a killer who sees through her armor and tempts her with a passion she's long denied.
Assigned to protect her legacy from ruthless enemies, Dylan must navigate a treacherous game of lies and rival hit men. Every mission drives them deeper into danger-and closer to each other. As bullets fly and betrayals surface, Sophia and Dylan must decide: do they follow their hearts into the fire, or will his deadly world consume them both?
The Assassin's Promise is a pulse-pounding romantic suspense about forbidden desire, shattered vows, and the ultimate risk of giving your heart to a killer.
